What is System Photo Library?
Before we start to fix this issue, let's take a complete understanding of the System Photo Library and learn how to designate a System Photo Library in Photos on your Mac/MacBook.
When using Photos for the first time, you can create a new library or select the one you want to use. This library will automatically become the System Photo Library.
Although you can use multiple photo libraries in Photos, the System Photo Library is the only one with access to iCloud services, including iCloud Shared Photo Library, Shared Albums, and My Photo Stream. In addition, some Apple apps and third-party applications can also access your System Photo Library using the Media Browser.
By default, your System Photos Library is stored in the Pictures folder on your Mac/MacBook, but you can move it to another location on your Mac/MacBook or store it on an external storage device.
You can follow the given steps to designate a System Photo Library in Photos on your Mac/MacBook:
- Quit Photos if it is open.
- Hold on to the option key to open Photos. (One of the photo libraries is already designated as System Photo Library.)
- Select the library that you want to designate as System Photo Library.
- Choose Photos > Settings from the Apple menu after Photos opens. (Or press Command + comma to open.)
- Hit the General tab and tap Use as System Photo Library.
If Use as System Photo Library is grayed out, it means the current library is already set as your System Photo Library.
After that, you can share your photos on different platforms or devices. And it's easy for your Mac/MacBook to choose a photo from the photo library without the need to ask for permission during selection.
